Concept explainers
Choose the best answer to each of the following. Explain your reasoning.
We can be sure that variation in Earth’s distance from the Sun are not the cause of the seasons, because (a) Earth is always exactly the same distance from the Sun. (b) if distance were responsible for the seasons, both the Northern and the Southern Hemisphere would have summer at the same time. (c) if distance were responsible for the seasons, seasonal temperature changes would be much more extreme.

- Kinetic Energy and Temperature: We will construct the algebraic relationship between kinetic energy and temperature for a gas from the ideal gas law, PV=NkT where P = pressure, V = volume, N = number of particles, k is Boltzmann’s constant, and T is temperature. Recalling that pressure can be expressed as P=F/A,where F = force and A = area, rewrite the ideal gas law in terms of Newton’s Second Law of motion in order to relate kinetic energy to temperature using dimensional analysis. (HINT: keep in mind the definitions of the kinematic variables and . Assume there is temperature associated with the kinetic energy in each direction [x,y,z] of motionarrow_forwardDirections: Read and understand the following questions below. Shade the circle that corresponds to the correct answer. 1. Which type of seismic wave travels the slowest? OP waves OS waves OSurface waves 2. Which type of seismic wave causes the most damage? OSurface vwaves OS waves OP waves 3. What do seismic P waves travel through? OLiquids only OSolids only OSolids and liquids 4. What causes seismic waves to travel in curved paths? OReflection ORefraction ODiffraction 5. What evidence do we have that the Earth has a liquid core? ORefraction of seismic waves OThe time lag between P and S waves The S wave shadow zonearrow_forwardDelay time for communication between GEO satellites and Earth. Use the relationship between distance (d), time (t) and speed (v), d = vt to repeat the calculation we did in class, but this time using the English units. Use the fact that GEO satellites orbit at 22,236 miles above Earth's equator, and that the speed of light is 1.86 x 105 mi/s. (Note that both of these values are equivalent to those used in class.) You may want to write this calculation on paper and insert a photo here.arrow_forward
